AWNING.

SZPECIFICATION forming part of Letters Patent No. 449,38'7, dated March 31, 1891.

Application filed May 27, 1890. Serial No. 353,357. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK SOHREIBER, a citizen of the United States, residing at Bridgeport,in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Awnings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has reference to awnings, but especially refers to the frame-work, whereby the proper shape of the awning is preserved, and has for its object to provide means for bracing the cross-bar of the awning, so that it will not sag, and also to do away with the extra brace-irons that are used in connection with longawnin gs, and, furthermore, to greatly lighten the framework of the awning and to render the elevation and lowering of the latter an easier task than heretofore.

In the accompanying drawings, Figure l is a detail plan of an awning-frame provided with my improvement; and Fig. 2, a view similar to Fig. 1, but showing the tightening-screw threaded at one end only, the other end being simply swiveled tothe adjacent nut.

Similar letters denote like parts in both figures of the drawings.

A are the side irons, and B the cross-bar, of an ordinary awning-frame.

C are brace-arms, which extend inwardly from the cross-bar, the extremities of said arms having notches or eyes a.

D are brace-wires secured at their outer ends to the side irons A and extending through the eyes a in the arms C. The inner ends of said wires are secured to separate nuts E, having right and left threads, respectively, and a screw F, having at its respective ends right and left threads to engage said nuts. A wrench-hold G is preferably formed at the center of the screw, and by manipulating the latter the wires may be drawn very taut. The irons A are comparatively short and are very stout, so that they cannot become sprung, and it will be clearly seen that any tendency on the part of the cross-bar to spring or sag will be resisted by the brace-wires D.

By providing a screw which has an efficient action at both ends I of course am enabled to draw the wires taut very quickly; but there is nothing novel in the use' of a screw having right-and-left threads, and therefore I do not wish to be confined to the use of such a screw in this connection, for if one of the threads be stripped from the screw and a head I) on the screw G formed at the end of such stripped part beyond the nut, as shown in Fig. 2, a swivel connection will be provided for the screw, and one end only of the latter will there by be efficient in operating to draw the wires taut, all of which will be clearly understood by reference to Fig. 2.

In fact, I do not wish to be confined to any particular arrangement and adaptation of a screw and nut as long as I limit my invention to the provision of two brace-wires, whichare secured at their inner ends to the complementary members of a nut-and-screw connection.

I claim 1. In an awning-frame, the combination of the side irons, the cross-bar secured thereto, thebrace-arms extending from said cross-bar, the brace-wires secured at their outer ends to the side irons and extending over the terminals of said arms, and a nut-and-screw con- .nection interposed between and secured to the respective inner ends of said wires, whereby the latter are drawn taut, substantially as set forth.

2. In an awning-frame, the combination, with the side irons and cross-bar, of the bracearms extending from said cross-bar and having eyes in their extremities, the brace-wires secured at their outer ends to the side irons and extending through said eyes, the nuts connected to the inner ends of said wires and having right and left threads, respectively, and the screw having right and left threads adapted to engage with the respective nuts, substantially as shown and set forth.

In testimony whereof I affix my signature in presence of two witnesses.
